Multiple files having the same name but a different case in different directories #50

Closed anthonyryan1 closed 7 years ago

I seem to be seeing an issue where multiple files having the same name (but with a different case) causes problems.

Reproduction steps: 

# within a newly created exfat mount
git clone https://github.com/torvalds/linux.git
cd linux
git status

Expected result

Now the pattern I saw here was that the problematic file names all appear with different cases within the linux code base here. I've tried recreating a few with the correct case and it appears to simply invert the case of the other file in those tests.

I've tested this on exfat 1.2.5 + kernel 4.9 and exfat 1.2.4 + kernel 4.4 to reproduce these results.

exFAT is case-insensitive by design. So, that's the expected behaviour.
